FLASH: Report into Casey Kearney stabbing released

Agencies missed opportunities to help a woman with a history of mental health problems who said she was going to harm someone, before stabbing a 13-year-old girl to death in Doncaster.

Hannah Bonser was jailed for a minimum of 22 years after being found guilty of murdering Casey Kearney in Elmfield Park on Valentine's Day.

Casey was going to a sleepover at a friend's house when Bonser - a total stranger with a diagnosed personality disorder and a history of cannabis abuse - stabbed her once with a 16cm kitchen knife she had bought earlier. More to follow.
